Abstract: A curable composition and a use thereof. As the curable composition is applied to a product that generates heat during the driving or maintenance process, it is possible to provide a curable composition that can be used as a material capable of treating the heat. The curable composition is applied to a product in which a plurality of elements generating heat are integrated, whereby it can efficiently treat the heat generated by the element while maintaining a uniform temperature of the product. In addition, even when the abnormal heat, explosion or ignition occurs in any one of the plurality of elements, the curable composition is applied to such a product, so that the effect of such heat, explosion or ignition to other adjacent elements can be prevented or minimized. The curable composition of the present application can also stably perform such a function over a long period of time.

Abstract: A curable composition and a use thereof. The curable composition can be applied to a product or an element that generates heat during driving, storage and/or maintenance, or has possibilities of ignition or explosion, capable of effectively responding to the heat, ignition, and explosion. For example, the composition is applied to an article comprising a plurality of products or elements as described above, thereby being capable of responding to abnormal heat generation, explosion, and ignition occurring in any one element or product, and preventing or minimizing propagation of such heat generation, explosion, and ignition to other adjacent elements or products. Also, the curable composition provides excellent handling properties, storage stability and flame retardancy. In addition, the curable composition or the cured product can stably maintain the above characteristics for a long period of time while achieving the above characteristics by using a non-capsulated phase change material.
